CONNECTIONS:
POWER INPUT: The standard model requires AC power input between 100 to 240 VAC 50/60Hz. No
adjustments are necessary for voltages within this range. Connect L (Live) N (Neutral) and AC Ground.
Optional DC input model requires 9-32 VDC/9 Watts. Connect to + and - terminals.
Optional Thermostat and Heater modules are available rated for 115 VAC or 230 VAC.
IMPORTANT NOTE: To comply with electrical safety standards, AC power input and relay connection
wires must have conduit entry to the instrument enclosure. Installation requires a switch, overcurrent
fuse or circuit breaker in the building (in close proximity to the equipment) that is marked as the
disconnect switch.
Risk of electric shock. Loosen cover screw to access connections. Only qualified personnel
should access connections.
Note: Use of instrumentation over 40°C ambient requires special field wiring.
Note: User replaceable fuse is 2 Amp 250V (T2AL250V).

MAIN DISPLAY
The main display shows the units selected from the Units/Mode menu, Flow or
Velocity rate being measured, TOTALIZER and RELAY states. The SFM 6.1
will start-up with this display.
MESSAGE ICON
Press from the main display to view status of the data logger and error/warning
messages provided by the instrument. The Message Icon will appear on the main
display if error messages are being generated by the instrument. Press to return
to the main display.
STATUS
Press from the main display to view instrument status. Velocity will be
displayed in ft/sec or m/sec.
Tot
Signal Cutoff
Signal Strength
Relays
20mA at
Displays the current totalizer reading.
Adjust the setting in percent to suppress flow
readings at zero flow when fluid swirling or pipe
vibration may cause the instrument to continue
reading. Example: Signal Cutoff at 5% will force the
display and outputs to zero when signal strength
drops below 5%.
Displays percentage of signal being received by the
ultrasonic sensor.
Energized relays will display as a white character on
a black background.
Displays the flow rate set as 20mA in the Calibration
menu. Press to return to the main display.

24 HR LOG (Data Logging option only)
Press from the main display to view a formatted flow report from instruments
with a built-in data logger. Press to scroll down one day or repeatedly to scroll
to a specific date. Up to 365 days can be stored. Newest date will overwrite the
oldest. Press to return to the main display.
PASSWORD
The password (a number from 0000 to 9999) prevents unauthorized access to the
Calibration menu.
From the main display press the key to get to Password. Factory default
password is 0000 and if it has not been changed press the to proceed to the
Menu Selections screen.
If a password is required, press to place the cursor under the first digit and or
to set the number, then to the second digit, etc. Press or to proceed to
the Menu Selections screen.
A new password can be stored by going to Special Functions/New Password.

UNITS/MODE
From Mode press the and then the or to select Flow or Velocity.
Flow mode displays the flow rate in engineering units (e.g. gpm, litres/sec, etc.)
Press the to store your selection then the to the next menu item and to
enter.
From Linear press the key and then the or to select your units of
measurement. Press the to store your selection.
Press the key to move the symbol to each subsequent menu item and the to
save your selections.
Note: the volume selection "bbl" denotes U.S. oil barrel.
Press or to return to the Menu Selections screen.

CALIBRATION
Press the to Calibration and to enter. Use or to position before
each menu item and to enter. When settings are completed press to store and
return to the Calibration menu.

Pipe ID
Damping
Pressthenorto change the numbers and decimal point.
Use this menu to set the corresponding flow rate that will be
represented by 20mA analog output. If maximum flow is
unknown, enter an estimated flow rate and observe actual flow
to determine the correct maximum value. Any velocity or flow
rate up to +40 ft/sec (12.2 m/sec) may be selected.
Pressorto set the flow rate corresponding to 4mA analog
output. This setting may be left at zero flow (or velocity or can
be raised to any value less than the 20mA setting, or lowered to
any velocity or corresponding flow rate down to -40 ft/sec
(-12.2 m/sec).
Pressand enter a minimum velocity cutoff. Forward and
reverse velocities less than Min Vel will be forced to zero.
Place the cursor under the digits and thenorto change the
numbers and decimal point. Pipe ID should be entered as the
exact inside diameter of the pipe where the sensor is mounted.
Refer to the Pipe Charts Appendix in this manual for inside
diameter of common pipe types and sizes.
Increase damping to stabilize readings under turbulent flow
conditions. Decrease for fast response to small changes in flow.
Damping is shown in percentage (maximum is 99%). Factory
default is 10%.

RELAY PARAMETERS
SFM 6.1 Slurry Flow Meter
Relay
Function
Flow
Pressandorto select a corresponding relay number (2
relays are standard, 4 additional are optional).
Pressorto select Off, Pulse or Flow.
Mode Select Pump, Low Alarm or Hi Alarm.
Pump mode provides separate On/Off settings where the
relay will energize at one flow rate and de-energize at another.
On Position the cursor under the numerals and press or
to set digits to the required relay On set point.
Off set digits to the required Off set point.
Low Alarm mode relay will energize at a programmable flow
rate and remain energized with flow below the set point. When
flow rises above the set point, the relay will de-energize.
Hi Alarm mode relay will energize at a programmable flow
rate and remain energized with flow above the set point. When
flow falls below the set point, the relay will de-energize.
Pulse
Pressand set digits to the flow volume increment required
between relay pulses. Use this feature for remote samplers,
chlorinators or totalizers. Minimum time between pulses is
2.25 seconds and pulse duration is 350 milliseconds.
Return to Relay and change settings for each relay number.
Press to return to Menu Selections.
